More a community experiment and also a case study but there will be a live broadcast (not sure yet how) the 25th of July providing you the insights of making the perfect extrusion screw for v3. The session is harder than the v4 screw (larger diameter = less shatter); we're still waiting for details from PP Eindhoven. Requirements 1. normal metal lathe which can deal with a 70 cm stock, 30 mm diameter, target pitch=22mm, please level her out and clean all the gearing and lead screws as well calibrate your tailstock. You also need an adjustable 4 jaw chuck in the 300 Euro range. The price is around 1000 - 2000 Euro for such lathe. Ideally you have a good inverter which enables you to add limit switches. Consider using the inverter brake function without resistor bank rather bad for your motor. 2. all the tools show below in the picture; notice the massive live center, get a new one; it makes a big difference. 3. stock : 30 mm diameter, chromoly or mild steel (hardening) 4. balls, it's dangerous and easy to make mistakes 5. time, the entire process last 9-12 hours but we record and document the more essential parts see you in a bit; if you miss the session, it's going into the wiki but it's better to be around live. this post will be updated with links and details the next days.
